Humidity, definition of
- Humidity
Humidity is a term for the amount of water vapor in the air,
and can refer to any one of several measurements of humidity. Formally,
humid air is not "moist air" but a mixture of water vapor and other
constituents of air, and humidity is defined in terms of the water
content of this mixture, called the Absolute humidity. In everyday usage, it commonly refers to relative humidity, expressed as a percent in weather forecasts and on household humidistat's; it is so called because it measures the current absolute humidity relative to the maximum. Specific humidity is a ratio
of the water vapor content of the mixture to the dry air content (on a
mass basis). The water vapor content of the mixture can be measured
either as mass per volume or as a partial pressure, depending on the
usage.
In meteorology, humidity indicates the likelihood of precipitation, dew, or fog. High relative humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table, used during summer weather.

- Lets the climate models tell the truth we want to see..
Climate models are just that, a model, based on assumptions and theories. Their accuracy is limited not only through the complexities of the climatic systems they model but also by the conclusions researchers want to see from them.. - More exact monthly means...
Following up with more data set pairs showing the difference in accuracy between min/max daily monthly means and taking the mean of all hourly measurements in that month.. - What exactly is a monthly mean?
A lot of climate analysis is done using the monthly mean temperature. Given that data is quite often available for hourly measurements I thought I'd have a look at whether creating a monthly mean straight off all the hourly measurements would produce a difference; initial findings indicate it does. - Australia has a growing obesity problem
